Where in Xiaomi files are saved: a full data storage map on smartphones Redmi, POCO and Mi

Have you downloaded a photo but can't find it? Or does the app save files "somewhere" but not in the folder you specified? Xiaomi smartphones (including Redmi, POCO and Mi) have strict file storage rules but are not always intuitive, especially when you consider that the manufacturer is actively using hidden folders, internal and external memory separation, and its own cloud services like the Mi Cloud.

In this article, we’ll look at all the possible ways to save files, from standard browser downloads to messenger cache and system logs, how to find lost data, why some files are duplicated, and how to transfer them to a memory card without losing functionality, and where Xiaomi hides backups of SMS and call logs that are not visible in the standard file manager.

Xiaomi Memory Structure: Internal vs External

Xiaomi smartphones divide memory into two types: internal (ROM) and external (microSD or microSD) OTG-The logic of saving files depends on the version. MIUI And the models of the device. For example, in the Redmi Note 12 Pro.+ s MIUI 14 the way to downloads is different from what was in the Mi 9 on MIUI 10.

Basic rules:

• 📁 Internal memory – divided into system and user partitions, access to system folders (e.g., system folders, /data) It is possible only with root rights.
• 💾 External memory (microSD) – formatted as portable or internal (extension of internal memory); in the second case, the card is encrypted and not readable on other devices.
• ☁️ Cloud Storage – Files from Mi Cloud, Google Drive or Yandex Disk are synced in the background and can be duplicated locally.

Importantly, if you connect a memory card as internal, the system automatically transfers some of the applications and their data to it, but not all programs support this feature - for example, WhatsApp or Telegram can refuse to work with external memory.

Standard ways to save files

Most files in Xiaomi are saved in /storage/emulated/0/ (also known as /sdcard/ in older versions of Android) as a virtual root directory of user data. Here are the main subfolders and their purpose:

Note that the Android/data/ folder is hidden by default, and to see it, you need to enable the display of hidden files in the file manager (for example, in Mi File Explorer or Total Commander).

⚠️ Attention: Do not delete the folder Android/obb/ — It stores additional data for games (e.g., graphics packages for Genshin Impact or Call of Duty Mobile) and will cause app failures.

Where Xiaomi hides hidden files and backups

The manufacturer backs up critical data -- SMS, call logs, notes, even some system settings -- that you can't see in the standard interface, but you can find them manually.

Main hidden locations:

• 📱 /data/data/com.android.providers.telephony/databases/mmssms.db — database SMS (Root rights are required).
• 📞 /data/com.miui.yellowpage/databases/yellowpage.db — call log (only for the purpose of MIUI).
• 🔄 /MIUI/backup/AllBackup/ — backup copies created through Settings → System system → Backup.
• 🔒 /mi_adb/ — folder for debugging logs (appears when activated) ADB).

To access these folders without root, you can use ADB-team:

adb pull /data/data/com.android.providers.telephony/databases/mmssms.db C:\sms_backup\

To recover SMS from mmssms.db, you will need specialized utilities such as SQLite Browser or SMS Backup & Restore.

Features of saving files in messengers

Each messenger uses its own media storage paths, and Xiaomi can redirect downloads to non-obvious folders, especially if the memory optimization function in MIUI is activated.

Where to look for files from popular applications:

• 💬 WhatsApp: /storage/emulated/0/WhatsApp/Media/ (Photos, videos, voice messages).
• 📤 Telegram: /storage/emulated/0/Telegram/ (Telegram Images folders, Telegram Video).
• 📱 Viber: /storage/emulated/0/Viber/media/ (Video and audio calls are stored separately).
• 🤖 WeChat: /storage/emulated/0/tencent/MicroMsg/Download/.

Important nuance: if you transferred the messenger to the memory card, the path will change /storage/XXXX-XXXX/Android/data/com.whatsapp/, where XXXX-XXXX — A unique card ID, with some files (such as Telegram stickers) still in internal memory.

⚠️ Attention: B MIUI 14+ Privacy Protection is enabled, which can block access to messenger folders via PC. To fix this, go to Settings → Annexes → Special permits → Access files and allow access for the file manager.

How to transfer files to a memory card without losing data

Many users face a problem: apps don’t see files on a memory card, even if they are physically there, because Android restricts access to external drives by default.

Instructions for transfer:

1. Format the card as internal storage (all data will be deleted!). To do this, go to Settings → Memory → SD card → Configure as internal memory.
2. Use Mi File Explorer to manually transfer files, such as moving the DCIM/Camera folder to a map, and then specify a new save path in the camera settings.
3. For applications (such as WhatsApp), back up, uninstall, and reinstall the program by selecting a memory card as a storage location.

If the card is formatted as portable, some apps (like Google Photos) won’t be able to automatically save files to it, in which case manual path indication in the app settings will help.

Why do files get duplicated or disappear?

Xiaomi users often complain of two problems: duplicate files (for example, the same photo appears in several folders) and the disappearance of data after updating MIUI.

• 🔄 Automatic sync with Mi Cloud or Google Photos creates copies in the cloud and locally.
• 📱 Optimization of memory in MIUI Can archive rarely used files (check folder) /MIUI/optimize/).
• 🔧 Update failures – if the update process is interrupted MIUI, The system can reset some of the user data.
• 🗑️ Cleaning the cache through Settings → Memory. → Clean sometimes removes files from application folders.

To avoid loss:

1. Turn off automatic sync in Settings → Accounts → Mi Cloud.
2. Before updating MIUI, back up via Settings → System → Backup.
3. Use third-party file managers (such as Solid Explorer) to find duplicates by hash.

💡

If files have disappeared after the update, check the /MIUI/backup/LastBackup/ folder – sometimes the system creates a temporary copy before installing a new version of MIUI.

How to find lost files: step-by-step instructions

If the file is missing but you are sure it was on the device, follow this algorithm:

1. Check the Recycle Bin: In Mi File Explorer, open the menu → Recycle Bin (files are stored there for 15 days). In Google Photos, check the Recycle Bin section (storage for up to 60 days).
2. Use search: In Mi File Explorer, tap on a magnifying glass and type in part of the file name. For deep search, install Root Explorer (root rights required).
3. Check out cloud services: Log into Mi Cloud via your browser (i.mi.com) and check the Gallery section. In Google Drive, open Backups → App Data.

Restore from backup copy

• Go to Settings → System → Backup → Restore.
• If the copy is damaged, use the Mi PC Suite to recover.

If a file was permanently deleted, try recovery software like DiskDigger, Recuva (for PC) or Undeleter, but the odds of success depend on how much data was written to the device after deleting it.

💡

The faster you start searching for a lost file, the better the chances of recovering it, and once deleted, the data stays in memory until it is overwritten with new files.
